Tampa Jvm User Group

Maven: The Intelligent Build System?

In this introduction to Maven session, I am going to discuss 3 build concepts that are central to Maven.  I will demonstrate how convention over configuration, a common build interface and universal reuse of build logic have come together to make the developers life much easier.  Building your Java project no longer needs to be a laborious process.  Maven's standard conventions, its common interface and its universal reuse of build logic will help you become a more productive developer.

• Is your app so brittle that if you stare at it for too long that it may break causing an all weekend outage?


• Does your app contain smelly dead code?


• Are your code review sessions a waste of your time?


• When you write apps do you just throw code together and hope for the best?


• Are you looking to convince your lead/architect to do things right the first time around?

If you answer YES to all of the questions above then you may have a code quality issue.  In this month's Tampa Java User Group meeting, we are going to look at Sonar, an open source code inspection tool.  Sonar packs a hefty dose of functionalities including design rules, metrics, test coverage, and an additional 40+ plugins to help you keep your code in top shape.  In this month's meeting, Speaker RJ Salicco will show you how to quickly download and throw Sonar at your code to get high quality reviews of your code base.

***  The June 2010 meeting will be held on Monday June 7 (not last Tuesday of month).  ***

This month we are going to discuss Ehcache 2.0, improvements in the Caching SPI, and how it can help you boost Hibernate performance by up to 10 times.  Speaker Greg Luck, from Terracotta, will be touring the states and will make a special stop in Tampa to talk about Ehcache.  While short notice, I am sure those of you in need of understanding and increasing Hibernate performance will attend.

Title: The new Ehcache 2.0.0 and Hibernate Caching SPI provider - Boost Hibernate Performance by 10x

Abstract: Ehcache is an open source, standards-based cache used in a wide array of applications to boost performance, offload the database and simplify scalability. Ehcache is robust, proven and full-features and this has made it the most widely used Java-based cache.

Greg will walk through the Spring Pet Clinic as an application example and show us how to tune it for maximum performance, both when using Hibernate and when caching result sets directly.  He will show us benchmarking tests the comparative application performance of Ehcache EX 1.8 versus MySQL, Memcached and a leading In-Memory Data Grid, including the impressive performance increases from the latest Terracotta 3.2 Server Array.  Finally Greg will also discuss some upcoming features in Ehcache 2.0 such as JTA, bulk loading, the new Hibernate 3.3 provider and write-behind.

For the May's meeting the Tampa Java User Group will cover the topic of RESTful web services.  If you attended last month's software symposium conference you know that REST is rapidly becoming the centerpiece for scalable architectures.  This month, speaker Cameron Ingram will provide a thorough introduction to REST using JBoss's RestEasy framework.  The meeting is scheduled for May Tuesday 25 and will be packed with useful information about REST web services constructions.

Last Tuesday (the 23rd of Feb) the Tampa Java User Group had a large turn out for the presentation on Hadoop.  Speaker Matthew McCullough did an outstanding job of effectively capturing the essence of a complicated subject in less than two hours.  The power of the technology was demonstrated when Matthew demonstrated Hadoop working on his laptop on problems that can easily scale to thousands of nodes.  We close the night with a drawing to the up coming Central Florida Software Symposium in April.  Congratulation to our winner.

-= Upcoming Events=-

• Our presentation for March 200 is being prepared now.  Once we get confirmation from the speaker, we Feffwill send out an event note.  Stay tuned for the announcement.


• Central Florida Software Symposium - we are privileged to host the Central Florida Software Symposium this year.  It will be held on April 16 -18.  Don't miss this opportunity to get recharged on the latest technologies and practices sweeping the industry.  The best part is it is local and you don't have to travel far.  If you are interested, see http://www.nofluffjuststuff.com/conference/tampa/2010/04/home for details.

Hello Java Developers,
Ever wonder how companies such as Yahoo, Google, Facebook, Amazon, financial organizations, and others are able to process large amount of data?  For our Feb 2010 meeting, Speaker Matthew McCullough, from the NFJS Java Software Symposium conference series, will do a presentation on distributed computing.  He will explore Apahce Hadoop, a production-ready Java framework that uses the MapReduce strategy to process large amount of data using grids of commodity machines.  The meeting is scheduled for Tuesday, Feb 23 and promised to be packed with interesting information to get you started with distributed computing.

Hadoop: Divide and Conquer Gigantic Datasets (Intro)
Moore's law has finally hit the wall and CPU speeds have actually decreased in the last few years. The industry is reacting with hardware with an ever-growing number of cores and software that can leverage "grids" of distributed, often commodity, computing resources. But how is a traditional Java developer supposed to easily take advantage of this revolution? The answer is the Apache Hadoop family of projects. Hadoop is a suite of Open Source APIs at the forefront of this grid computing revolution and is considered the absolute gold standard for the divide-and-conquer model of distributed problem crunching. The well-travelled Apache Hadoop framework is curently being leveraged in production by prominent names such as Yahoo, IBM, Amazon, Adobe, AOL, Facebook and Hulu just to name a few.

In this session, you'll start by learning the vocabulary unique to the distributed computing space. Next, we'll discover how to shape a problem and processing to fit the Hadoop MapReduce framework. We'll then examine the incredible auto-replicating, redundant and self-healing HDFS filesystem. Finally, we'll fire up several Hadoop nodes and watch our calculation process get devoured live by our Hadoop cluster. At this talk's conclusion, you'll understand the suite of Hadoop tools and where each one fits in the aim of conquering large data sets.

For our first meeting for 2009, we will start the year with a practical look into JavaFX, Sun/Oracle's rich client platform.  While the platform is still in its infancy, it is robust and stable enough for production-ready applications.  In this presentation, we will explore how to quickly get started and provide a practical overview of the key features of the platform for building rich client applications.  The meeting is scheduled for Tuesday, January 2010.

-= Presentation =-
The JavaFX platform is Sun's answer to Adobe Flex/Air and Microsoft Silverlight rich client platforms.  JavaFX is comprised of a set of build/deploy tools, the JavaFX Script language, and a unified multi-device runtime.  With JavaFX, you write your code once and the build tools figures out how to target either mobile/entertainment devices, desktop, or a web browsers.  The JavaFX Script language is a domain-specific language designed to create interactive graphical applications running on the Java VM.  While the platform is in its infancy, the current version provides a robust and and production-ready environment on which you can build highly interactive rich desktop clients with compelling user experiences. This presentation is a compressed view of the major features of the JavaFX platform that you will find useful to get started.

- About JavaFX
- Quick Language Tour
